Garbage Fart: an expulsion of gas fueled from several days of a junkfood only diet.

Travis unleashed a volatile concoction of gases via rectum. It was the dreaded "GARBAGE FART". The smell, largely fueled by pringles (sour cream, cheddar and original flavors), sharks gummi fruit chews, a pound of bacon, and peanut butter was near deadly. The air around the campfire no longer smelled of smoke, but reeked of rotten swine and processed potato products.
